Dido, in Roman mythology, queen of Carthage, also called Elissa. She was the daughter of a king of Tyre. After her brother Pygmalion murdered her husband, she fled to Libya, where she founded and ruled Carthage. According to one legend, Dido threw herself on a burning pyre to escape marriage to the king of Libya. In the Aeneid, Vergil tells how she fell in love with Aeneas, who had been shipwrecked at Carthage, and destroyed herself on the pyre when, at Jupiter's command, he left to continue his journey to Italy.

In Greek legend, the founder of Carthage. She fled to North Africa after the murder of her husband and bought land from a local chieftain, Iarbas. She killed herself rather than marry him.
